×2 on packtalk bold , we've used collett, and scala riders , over the years all have plus and minuses... last year we we're in -30c and by 3pm the packtalks were shutting down with low battery, so this year ive bought a power pack to charge them at lunch time. The range on packtalk is around 1 mile unlike the collett's which is about 2 miles. But if there's a group of you the packtalk has mesh connect that bounce the signal from one rider to the other.... but at the end of the day you pays your money and make your choice... and adapt to using the system..
